Spatiotemporal Semantics and Moving Objects Research

Kathleen Stewart

  • Continuants - statically located
  • Occurrents - happen and then gone
    • traffic jams
    • volcanic activity
  • Conintuants -> objects
  • Occurents -> events
  • Geospatial Eventes model
    • objects & events create settings (more situational, spatiotemporal)
    • increasing granularity
  • Geospaital domain
    • Uses a harbor
    • Partitioned into zones
    • Zones break down into:
      • departure vs destination
    • Movement through zones constitutes an event
  • Events become sequences
    • Referred to as a transit
    • Basically a series of states
  • Generalization of Events
    • Expected, routine behaviors for abstraction
    • Unexcepted behaviors
      • Rerouting
      • Abort
  • Patterns of events
    • Collocating pattern
    • Repeating patterns
  • Starts to get interesting *
  • Orientation plays into this
    • uniform/random/Follow the leader/etc
  • Branching events
    • Apply ML
      • potential future events
      • past events
  • Integrate branching/non-branching to form a more complete overview
    • 911 scenario
    • What If scenarios
  • Persistence of geographic features over time
    • Things aren't as permanent as they seem.
  • Spatiotemporal IR
    • NLP processing + Geo
    • Derive maps from the context
